The utility model relates to the technical field of natural gas pipeline valves, and discloses a gas synchronous pressure maintaining self-closing device which comprises a gas closing valve body, a lifting valve rod is arranged at the top of the gas closing valve body, the right end of the gas closing valve body is communicated with a gas inlet pipeline, and the left end of the gas closing valve body is communicated with an exhaust pipeline. According to the gas synchronous pressure maintaining self-closing device, by arranging the gas closing valve body and the lifting valve rod, when the gas supply pressure of a pipeline is under-pressure or over-pressure, the gas synchronous pressure maintaining self-closing device can be automatically closed without electricity or other external power, and by arranging a buzzing warning lamp, a gas pressure sensor, a temperature sensor, a detection head, a control circuit board, an intelligent detector and a signal transceiver, the gas can be automatically closed; accordi
